More on PerfHUD 6.5

• Better control via PerfMarkers: add them now!• API time graph• More performance hints: VSync on, windowed mode, event queries,

not all render targets used, VBs not managed, etc.• Subtotals in Frame Profiler• Break (_int 3) on draw call• 32bit apps on 64bit Oss• Save/Load DX10 frame captures (Ctrl+S in the Frame Debugger)

PerfKit: Features

• PerfSDK• Real time performance information in your game• Driver data, GPU counters, etc.• Simplified Experiments for easy bottleneck analysis• Simple API, code samples and helper classes

• GLExpert• Detailed feedback on pipeline setup• SLI performance feedback• Warnings for software fallback• VBO/FBO performance information

• Microsoft PIX for Windows plugin• GPU & driver counters alongside PIX data

VRD for PhysX

VRD

• VRD: Visual Remoter Debugger• A very useful tool for problem-solving

• Functionalities• Visualize PhysX objects to give you a pure physics world• Show detailed information of PhysX objects• Record detailed simulation status and can playback• Interact with game at real time when recording

Profiler shows Profiling data each frame

Event List shows events each frame

Here visualizes you the PhysX world

Scene Browser tells you detailed info of PhysX objects

AgPerfMon for PhysX

AgPerfMon

• AgPerfMon• a comprehensive profiling tool for physics applications

• Functionalities• Powerful event-logging allows you to understand exactly how your application

is using PhysX • Event Viewer displays a Gantt chart of all events • Handy utility allows you to export your data to a graph, or to a comma-delimited

format (CSV)

PhysX profiling zones

Chart shows clearly the time a profiling zone consumes
